Summary
This study reviewed orthognathic surgery outcomes over six years, finding that most patients achieved corrected occlusion. While complications like bleeding and nerve injury occurred, relapse rates were low, indicating successful surgical interventions.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Plastic Surgery
Background:
- Orthognathic surgery corrects significant jaw discrepancies and improves facial aesthetics.
- A single surgeon's experience provides a focused perspective on surgical outcomes and complications.
- Understanding outcomes in a diverse patient cohort is crucial for surgical planning.
Purpose of the Study:
- To audit the outcomes of orthognathic surgery performed by a single surgeon over a six-year period.
- To analyze the types of procedures, patient demographics, and predisposing conditions.
- To evaluate postoperative results, including occlusion, relapse rates, and complications.
Main Methods:
- Retrospective review of orthognathic surgery cases from January 2000 to January 2006.
- Inclusion of 102 patients (37 male, 65 female) with a mean age of 20 years.
- Analysis of surgical procedures (Le Fort I osteotomy, bimaxillary osteotomy), indications, and complications.
Main Results:
- Class I occlusion was achieved in 92 patients postoperatively.
- A low relapse rate of 4.9% (5 patients) was observed, with one requiring reoperation.
- Complications included excessive bleeding (3 patients) and inferior alveolar nerve injury (1 patient).
Conclusions:
- Orthognathic surgery, particularly Le Fort I and bimaxillary osteotomies, can yield high rates of successful occlusion.
- Careful surgical planning and execution are essential to minimize risks like hemorrhage and nerve injury.
- The study highlights the effectiveness of orthognathic surgery in correcting complex dentofacial deformities.
